Back to school after Christmas and the New Year
Year after year students change schools and publisher appear to change text books
Before you buy think a little, look at the schools required list. See if the book is avaliable on ebay or find out from the publisher what changes have been made to earlier versions to see if it justifies buying a new book. You could buy the earlier addition and your child could make arrangement to get the up dates if and when needed. Teacher use different books at different schools whilst the curriculum is state wide.
School books do not actually change alot from year to year they do over a five to ten year period. The biggest change appears to be the covers.
Hope this helps you save a little money
All the best
